Hello. I use the latest version of Rapidminer, in the documentation there is an operator that I do not have and I can not find it. Does anyone know where to find the X-Prediction operator?

    Hi the X-Prediction operator was merged into the new Cross Validation operator.  Check out the changelog here: http://docs.rapidminer.com/studio/releases/7.3/changes-7.3.0.html

    Thanks for the help, I'm new to data mining, I'm following your videos, they really help a lot of beginners like me. I'll look at the documentation. good weekend

    Thanks for that helpful reply, Thomas.

     

    Is there any way to label the examples with the predictions - after the cross validation operator?

     

    If I use the "exa" output, I only see the examples, but without the predicted labels.

     

    If I save the model after the cross validation operator and then apply it to the same data set and use the "Performance" operator, I get labeled examples - but the accuracy is way higher than the results from the cross validation.

     

    My objective is to get the predicted labels of the examples, which match the performance vector, which I get from the 5-fold cross validation. Is that possible?

     

    Thanks in advance!

    Dear Jochen,

     

    the predicted examples are delivered at the "tes" port. they are only calculated if this port is connected.

     

    Best,

    Martin
